1.
If you are converting an existing pump, remove
the suction hose (21) from the pump’s fluid intake.
See Fig. 2.
2. Unscrew the swivel elbow (G) from the end of the
suction hose (21) and discard the elbow. See Fig. 2.
Screw the rigid end of the manifold (29
) onto the
pump intake, and attach its swivel end to the suction
hose (21). See Fig. 3.
3. Screw the mounting stud (34
) into the outlet in the
base of the back pressure regulator (33
). Install the
fluid pressure gauge (38
) in the inlet of the back
pressure regulator. Remove the plugs from the op-
tional inlet and outlet of the back pressure regulator.
Install one 1/4 npt nipple (11
) in the regulator’s op-
tional outlet (J), and the other 1/4 npt nipple (11
) in
the optional inlet (H).
4. Place a lockwasher (35
) and washer (36
) on the
mounting stud, and insert the stud through the
mounting hole in the right side of the pump wall
bracket (7). Secure the regulator with a lockwasher
(35
) and nut (37
) on the inside of the pump wall
bracket.
5. Install the CIRC end of the three-way ball valve (30
)
in the open port of the pump fluid intake manifold
(29
). Screw the elbow (40
) onto the IN branch of
the three-way valve. Connect one end of the hose
(32
) to this elbow, and the other end to the nipple
(11
) at the back pressure regulator’s optional outlet
(J).
6. Connect the drain hose (31
) to the DRAIN end of
the three-way valve (30
).
7. Connect the fluid return line to the nipple (11
) at the
back pressure regulator’s optional inlet (H).
8. Connect the air and fluid hoses and gun as explained
on page 7.
